Specification of Letters Patent.

ratented 11131114, 1222.

Application filed May 20, 1921. Serial No. 471,114.

objects of cleanly and safe preservation of the material and the easy and convenient withdrawalof such thereof as may be desired from time to time may be attained. M'y copending and allowed application Serial No. 877,509 filed April 29, 1920 illustrates a filing cabinet provided at its upper end with a relatively small auxiliary cabinet having means for holding. rolls of blue print 3a erxtracin v 8.381 etc. The accom )anv-' a V a mg drawings are to be understood as showing framentarily the upper end portion of such a larger cabinet, and, while in its general aspect the present application is similar to myv said copending application, I haveshown herein the roll-holding and material-depensing features in an improved and,

preferred construction.

In these drawings, Figure 1 is a top plan of the cabinet Fig. 2 is a similarview with the topcover removed; and. Fig. 3 is a vertical transverse section as on the line 33 of Fig. 2'.

The present improvementscomprise or are included within the relatively small cabinet A well outlined in Fig. 3. It has-a top wall 10, a bottom wall 11, a rear wall 12,

a front wall 13 and a pair of outer side walls 14. The cabinet thus defined is relatively longin the horizontal directions so as to accommodate relatively long rolls of blue.

print paper, tracing paper, tracing cloth or form. Cabinet A is also relatively low in the verticaldirections. In my practice it is made as a unitary structure except as to the top wall 10 and the front wall 13, which are also parts of the larger cabinet B, and this unitary structure is secured in the top portion of the larger cabinet 13 as shown. 7 g I The top wall 10 has a hinged door 15 through which the-rolls 16, 17 and 18 of thin and flexible material may be inserted Between the outer sidewalls l t'there are two intermediate walls 20 which have substantially the same shape as the outer side walls 14. These inner side walls 20 are rigidly secured to the bottom wall 11 and to the rear wall 12, as are also the outer side walls 14;, a space being provided between each inner side wall 20 and the ad- .jacent outer side wall 14.- At a somewhat upper and rear location in the cabinet at rod-like member 22, in mypractice around 1 wooden bar, is secured rigidly to the inner side walls 20 and ate middle upper portion otthe cabinet the ,rod 23, in my practice a piece of metal tubing, is similarly held by and between the inner side walls 20.- These rods 22 and 23 are substantially parallel with the axes of the rolls 16, 17 and 18.

At a somewhat forwardv portion of the cabinet the. vertically positioned wooden -strip 24 is secured rigidly between and held by the inner 'sidewalls 20*. Two rests or supports 25, inmy practice metal tubing,

. extend from the rod-like member 22 forward to the strip 24:.

It is thus clear that the bottom wall and the'rear wallfl2of the smaller. cabinet carry the, inner side walls 20, and that these in turn carry the several parts 22, 24 and 25, the last three constituting a frame which supports the rolls of sheet material,- this frame extending downwardly and forwardly whereby the roll as; 16 will rest against the front strip 2 1, the roll 17 'resting against the roll 16 and the roll 18 resting, against the .roll. 17, the several rolls being held which carries at each end at rightangles to its longitudinal direction a triangular shaped sheet metal arm 27 which extends'to the lower rear corner of the cabinetbetween the side walls 14 and 20 and is therepivoted by a screw at 28 .to the'side wall 20. Theboard or door- 26"may therefore swing upl. ward into its dotted line position shown in Fig. 3, exposingarelatively long. andnar row opening in the lower front portion of the cabinet sutficient to permit a hand to be inserted for picking up one or another of the end portions of the sheet material lying adjacent to the opening on the bottom 11. The side walls '14Eandf20ihave theirjfront edges cut on an arc to correspond with the movement of the door26, aswcll illustrated in Fig. 3.

T he rodlikemembersQQ and 23 .are-sheetdeflecting devices and are employed vso asto enable a direct pull to be made upon any particular piece of the sheet material at the door opening in front for drawingsome of the material off of a particularroll for use, and to cooperate inproviding an arrangement whereby a pull upon the material of one roll will not causethe material of another roll to comealong with it. From Fig.

3 it will be observed that the material from the rearniostroll .18 is first carried over the deflector 23and thence over the deflector 22; that thereupon the material of the roll 17 is laid upon thematcrialifromtheroil ,18, and finally the material from the roll j 16.is

I laid upon the material from vthe roll -17,

these .three plies of the magma passing partially around each of the deflectors 23 and 22 insequence, and the plies extending forward to thedischarge door opening.

Suppose now it bedesired to Withdraw some of the material from the -.-roll,18. A pull upon the material of that roll, ,namely, the topmost ply near the/do0r26, will naturally result in a tendency to pull along with it the material of the second or middle ply, owing to the frictional contact between the two. This doesnot take place, however, for. it will be noted that apull upon the topply material extending from the roll 18 will turnthat roll in an anti-clockwise direction as viewed in 3, while the frictional 40 tendency to pull off simultaneously some oi the material from the adjacent roll 17 tends to move that roll in the same anti-clockwise direction. 'The result is that these rolls move in opposite directions where they con- .tac-t each other and the friction-there developed .is sufficient; to preventrthe material fromthe roll '17 zfromwcoming out of the cabinet when a pull is madeupon the ma terial of the-roll 18.

For'the same mechanical reasons, whicheverstrip ispulled'upon'at the discharge opening the material fromthat roll only comesout. 7

The upWardlyeand-downwardly swinging "board'26 has 'been'described herein as a door,

and it has the 'function of closing, the'discharge opening of cabinet'A when thedoor. 30 I of c'abinetfB is open. The board or. door, 26

has, however, a Zfurther. important function.

Its lower edge at 31 is planed straight and constitutes a straightee'dge. This straightedge portion of the d0or'26 at 31 overlaps thefront edge of the bottom'll at 32 to a limited extent whereby a portion ofthe bottomie'dge at 32 is exposed below'the edge 31. This construction and arrangement are provided to facilitate the separation "from part thereof which has been withdrawn for use. ln'operation-the door 26 is first lifted suiiiciently to enable the hand to select the the-sheet material Within the cabinet of that i material1to be withdrawn and the desired amount .of material is then simply pulled out. Thereupon the door 26 is allowed to descend, and in doing so it. clampsthe material between the closely contiguous over lapped parts-3l and 32, and thereupo-mif the strip material be paper, itmay simply vbe torn OH, and with a. clean edge, while, in

the case of such material as tracing cloth,

a knife blade may be passed along the .easy and; expeditious Way.

Various modifications and departures from what isherein-specifically illustrated and described arecon-templated by me as being within the invention herein set forth,

.asjndicated, in the appended claims.

.I. claim .1. ,A holder forv rolls ,of thin ancbflexible sheet material comprising vin combination means for supporting a plurality of such rolls'side byside in frictional contact-with each other,and a rod-like sheet-materialwde- 'flector spaced from, .andextending substantiallyparallel to the axesrespectivelygof the rolls when normally positioned on said supporting means.

2. T-he combination of Walls forming a cabinet having an opening through which relatively wide sheet material may bedrawn, means withinthe cabinet for supportingside by. side a. plurality of rolls of-thin and fleX- iblesheet material and a sheet-deflecting. device extending substantially parallel to the axes of the, rolls Whennormally positioned on, said supporting means, thearrangement being such that sheet materiahfrom eacheof isaid rollsmay pass partially around said deflecting device, withone vsheet upon an- -other, and extend therefrom to saidgopening.

porting loosely side by side against.,each other a plurality of rolls of thinandlflexible sheet material, the cabinethavingan opening through which such sheet material. may be drawn for use, a pair of rod-like sheet 3 The combination of walls vforming a a cabinet, means within the cabinet for sun deflecting devices extending substantially parallel to the axes of such rolls when normally positioned on said supporting means, said deflecting devices being so positioned that sheet material from any and all of the rolls on said support may extend partially around the one of said deflecting devices and then extend to and pass partially around the other thereof and extend thence to said openmg.

4:. lhe combination of walls forming a cabinet downwardly-and-forwardly-inclined means within the cabinet for holding side by side against each other a plurality of rolls of thin and flexible sheet material, the cabinet having a lower front opening through which the sheet material may be drawn, an upwardly and-downwardly swinging door for said opening, the lower edge portion of said door being substantially straight and overlapping a closely contiguous part of the cabinet where the sheet material issues therefrom whereby when said door is in such overlapped relation such sheet material may be clamped between the door and said contiguous part and be held while the exposed part of the sheet material is severed from the part thereof remaining withinothe cabinet,

a rod-like sheet-deflecting device positioned above and substantially parallel to the axes of such rolls when normally positioned on said roll-holding means, and a similar sheetdeflecting device positioned normally rearwardof the rolls.

5. The combination of top, bottom, side, front and rear walls forming a cabinet relatively wide in the horizontal directions-and relativel low in the vertical directions,

means within the cabinet for supporting side by side a plurality or rolls of thin and flexible sheet material, the front wall of the cabinet having a relatively long and narrow opening through which such sheet material may be drawn for use, a relatively long and narrow swinging door for the front opening, said door being arranged to clamp projecting sheet material for severing the same, the top wall also having an opening and a door for same.
